Abstract

Mediator is an essential component of the RNA polymerase II general transcriptional machinery and plays a crucial part in the activation and repression of eukaryotic mRNA synthesis. The Saccharomyces cerevisiae Mediator was the first to be defined and is a high molecular mass complex composed of >20 distinct subunits that performs multiple activities in transcription. Recent studies have defined the subunit composition and associated activities of mammalian Mediator, and revealed a striking evolutionary conservation of Mediator structure and function from yeast to man.
